The higher the complexity and sophistication requirements of steel structure building design, the higher the requirements for detailed design. Because the detailed design determines whether a place is finally confirmed and its quality. In modern steel structure buildings, various metal structural members and the details of the nodes connecting the metal members are often exposed, giving the building a strong sense of technology, such as the Pompidou Art and Culture Center in Paris, which was built in 1977, France , Its steel columns, steel beams, trusses and other structural components are exposed, which not only reflects the beauty of technology, but also reflects the wisdom and ability of people. Therefore, it is very important for steel structure buildings to maintain high design requirements for detail quality, and special attention should be paid to steel structure buildings.

Because steel structure building design has the general attributes of architectural design, architects do not design as they please. The owner's design task book plays a significant role in the architect's plan and design concepts. Clients hope that designers have better performance, and that both designers and market experts can participate in decision-making more efficiently in the process of determining their final products. At this stage, the construction project emphasizes the overall design and the coordination between professional designers, market experts and developers. The design process includes continuous information and knowledge exchange and integration. In addition, the specialization of steel structure buildings can not only provide a wealth of design knowledge, but also effectively integrate design resources and market experts who are responsible for the building, so that the design and the owner’s business intentions can be effectively combined to make the project profitable and reduce risks.

2. Steel structure building can meet the requirements of super height and super span. The structure of the steel is uniform, close to isotropic homogeneous body, with high strength and high elastic modulus. The ratio of density to strength is far less than that of masonry, concrete and wood. Under the same stress condition, the steel structure has small self weight, so it can be made into a structure with large span and high height and flexible structural form. At present, human beings have the ability to build super large domes with spans of more than 1000 meters and super high-rise buildings with heights of more than 1000 meters and up to 4000 meters. In addition, the cable membrane structure system formed by the combination of steel cable and membrane structure can better meet the span requirements of the building, making this type of building become a landmark building. For example, the roof of the baseball stadium in Tokyo back Park, Japan, is a cable membrane structure composed of steel cable and air bearing membrane, covering an area of 28000 square meters. The British government has built a landmark building for the 21st century, London Millennium Dome - a large-scale comprehensive exhibition The building is also a cable membrane structure system with a dome diameter of 320m.
